How to Write a Demand Letter to a Landlord in Missouri

When issues come up with your rental—like delayed repairs, concerns about eviction, or rent increases—it's important to communicate formally with your landlord. In Missouri, a well-written demand letter can help you clearly state your concerns, protect your legal rights, and lay the groundwork if you later need to pursue action through the courts or with the Missouri Attorney General’s Consumer Protection Division. This guide covers everything you need to know about drafting a demand letter as a Missouri renter.

Why Send a Demand Letter to Your Landlord?

A demand letter is a formal written request asking your landlord to address a problem. This step is usually required before escalating your dispute to legal authorities or filing a complaint. Common reasons Missouri renters send demand letters include:

  • Requesting repairs for unsafe or uninhabitable conditions
  • Disputing wrongful eviction notices
  • Challenging unfair rent increases
  • Requesting the return of your security deposit

Taking this step documents your concerns and shows that you've tried to resolve the issue amicably.

Key Elements to Include in a Missouri Demand Letter

A complete demand letter should be clear, factual, and concise. Essential elements include:

  • Your name, address, and contact information
  • Landlord's name and address
  • Date of writing
  • Clear statement of the issue (e.g., "My air conditioner has not worked since June 1st.")
  • Reference to the lease and Missouri law (e.g., citing the Missouri Revised Statutes § 441.234 for landlord repair duties)
  • What you are asking the landlord to do (specific repair, return deposit, etc.)
  • Reasonable deadline for response (e.g., "Please respond or make the repair within 14 days.")
  • Polite, professional tone
  • Your signature

Missouri Official Forms for Renters

While Missouri doesn't require a specific "demand letter form," certain disputes (like non-return of security deposit) may require formal documentation for small claims court. Missouri's courts provide guidance on preparing evidence and filing:

  • Small Claims Petition (Form SC-40): Used if your demand letter does not resolve the issue and you wish to file a claim (e.g., for a security deposit).
    Example: If your landlord doesn’t return your deposit after you’ve sent a demand letter and waited at least 30 days after move-out, you can use Missouri Small Claims Petition Form SC-40 to file in court.

If you are experiencing discrimination, you may also submit a complaint to the Missouri Commission on Human Rights.

How to Write and Deliver Your Demand Letter

Taking the time to properly write and deliver your letter strengthens your position. Follow these steps:

  • Be clear and stick to the facts.
  • Reference relevant Missouri statutes or your lease where possible.
  • Send the demand letter by certified mail with return receipt requested, or deliver it in person with a witness if possible.
  • Keep a copy of everything you send for your records.
If your landlord doesn’t respond, your demand letter becomes key evidence if you later need to file with small claims court or another authority.

Who Handles Landlord-Tenant Disputes in Missouri?

Missouri does not have a dedicated residential tenancy tribunal. Most disputes are handled by the Missouri Circuit Courts (including Small Claims Court). For complaints about habitability, discrimination, or security deposits, you can also contact the Missouri Attorney General’s Consumer Protection Division.

For an overview of your rights and landlord obligations, see the Missouri Revised Statutes, Landlord-Tenant Law.

Relevant Missouri Tenant Laws

The main state law for Missouri renters is the Missouri Revised Statutes Chapter 441 – Landlord and Tenant. This legislation covers everything from repairs to evictions and deposit refunds.
